Check engine light and others

2004 FORD EXPLORER

59,000 MILES

Hello,

My 04 explorer gives me the Service engine soon light every so often. I got codes P2106 and P2135. Once in a while the wrench light comes on too. The ABS light comes on when I floor the gas. The cruise control almost never works. Once in a while it might work. Engine performace seems to be ok no matter lights on or off. Car is tuned up.

I read in your post someone having very similar problem to mine (all issues mentioned above) and you recommended per Ford TBS to replace TPS. Is that the only thing to be replaced or should the throtle body also? Throtle body contains besides TPS TAC which from what I've read also could be part of problem?

Haynes says to backprobe TPS with multimeter. Haynes says TPS has 3 wires but mine has 4. Not sure how to proceed.

TPS costs 75 bucks but throtle body is about 300. I'm inclined to go ahead and replace TPS but need to be sure. Don't want to find out later I needed to replace TB.

Question is which one should I replace?

Please see below question and answer provided by one of your experts on issue like mine.

Thanks a bunch for your help on this.

Steve.

2004 Ford Explorer Problem

Upgrade Question

The first time it went into fail I was going 65 with
cruise control on. Cruise went off and ABS light came
on. A couple minutes later it went into fail mode with no change in engine performance. Than service engine light came on. I drove an additional 60 miles home. The next morning no warning lights, and drove a few miles and agin fail mode. I checked the computer codes and got one code P2106, which indicated throttle actuator control system. I reset the computer and drove several days with no problems. I called two ford dealers and was told the in the fail safe mode the vehicle should have performance reduction. Yesterday while in a parking lot the fail mode once again appeared with no service engine light. Restarted engine and everthing OK. Any ideas? thanks
of warning

Based on the codes and trouble symptoms, the TPs should be the component to be replaed only and if there is anything wrong with the TB, that should be another preoblem not related to what you are experiencing now.

The throttle body itself does not have much things to go badand seldom requires replacement.
